FIG. 6.

Gene dosage varies twofold within a population of growing bacteria. Left, the genomic region of a specific gene in the E. coli chromosome is fluorescently labeled in live cells. Right, the number of gene copies in cells about to divide (“long”) is double that of newborn cells (“short”). Figure adapted from (Sepúlveda et al., 2016). Reprinted with permission from AAAS.
